When it comes to photo engraving, the best type of wood largely depends on its density, grain, and finish. Basswood is often considered the top choice due to its fine grain and light color, which allows for detailed engravings without the risk of dark spots. It engraves smoothly and is easy to work with, making it ideal for high-resolution images.

Maple is another excellent option, known for its durability and light color. It has a slightly tighter grain than basswood and can produce sharp and detailed results. Cherry is favored for its warm tone and beautiful aging process, although it might produce darker engravings compared to lighter woods.

Birch is also a candidate, especially its plywood variants, which provide a smooth surface for engraving. On the other hand, avoid woods like pine and oak, as their knots and coarse grain can lead to less precise results.

Ultimately, the choice of wood for photo engraving should consider the desired aesthetic and the quality of detail needed in the final product.
